Laser cutting technology and welding technology
Laser cutting technology is widely used in the processing of metal and nonmetal materials, can greatly reduce the processing time, reduce processing costs, improve the quality of the work-piece. Modern laser became people’s pursuit of “standing” fantasy “sword”.
Laser cutting is the high power density energy produced by laser focusing. Under the control of the computer, the laser discharge is made by pulsed laser, and the output is controlled by a pulse laser, a certain frequency and a certain frequency, the pulse laser beam passes through the optical path, and the reflection and reflection are focused on the surface of the object. Every high energy laser pulse is a tiny hole in the surface of the object, which is controlled by the computer, and the head and the processed materials are continuously compared with the corresponding movement in advance. Cutting, a coaxial air flow from the cutting head, the melting or classification of material from the bottom of the cut out (Note: if the gas and the cutting material to produce thermal reaction, then this reaction will provide the additional energy needed to cut; air flow and cooling has cut surface, reduce the heat affected zone and ensure that the focus lens is not contaminated. Compared with the traditional method of sheet metal processing, laser cutting has the advantages of high cutting quality, narrow width, small heat affected zone, small incision, high cutting speed, high cutting speed, high cutting speed, high cutting speed, high cutting speed, wide range of material adaptability. To my company CO 2 laser cutting machine as an example, the whole system is composed of control system, motion system, optical system, water system, smoke and air blowing system for the protection of by the most advanced numerical control mode to realize multi axis linkage and laser without affecting the speed of energy cutting, while supporting EXP, PKT, CNC and other graphics format and strengthen the interface graphics processing ability; good in high speed motion accuracy is achieved by using performance superior imported servo motor and drive guide structure.
Laser welding technology
Laser welding is one of the most important aspects of the application of laser material processing technology. The welding process is heat conduction type, that is, the surface of the laser beam, the surface heat transfer through the heat transfer. Due to its unique advantages, it has been successfully used in the welding of micro and small parts. The emergence of high power CO 2 and high power YAG laser has opened up a new field of laser welding. The deep penetration welding, which is based on the small hole effect, has been widely used in machinery, automobile, steel and other industrial sectors.
It is difficult to weld the parts that are difficult to be welded. In YAG laser technology, optical fiber transmission technology is adopted, which makes the laser welding technology has been widely used and popularized. Laser beam is easy to realize the beam by time and space, can carry out multi beam simultaneous processing and multi station processing, which provides the conditions for the more precise welding. Compared with other welding technology, the main advantages of laser welding are: laser welding speed, deep, deformation is small. Can be welded in room temperature or special conditions, welding equipment device is simple. For example, the laser through the electromagnetic field, the beam will not drift; laser in the air and a certain kind of gas environment can be applied, and can be through the glass or transparent material for welding.
